About the Observed Trends

The Observed Trends report is one of four scientific reports that have been published on UKCP09. The report discusses observed (past) UK climate trends, to provide historical context for the future climate change projections presented elsewhere in UKCP09.

As well as providing this historical climate context, the Observed Trends report provides graphics of climate trends and datasets for the baseline period of the UKCP09 projections (1961 to 1990). These have been selected to cover as many as possible of the same variables as are covered in the UKCP09 future projections.
